Update one JSON file values with values from another JSON using JQ

Question

So I have two JSON files:

bosh.json:

{
  \"key_pair_name\": \"my-aws-keypair\",
  \"ssh_private_key\": \"my-key-name\",
  \"trusted_certific         


        

Answer 1

jq solution:

jq --argfile bosh bosh.json 'with_entries( 
         if $bosh[.key] then .value = $bosh[.key] else . end)' model.json

The output:

{
  "trusted_certificates": "my-trusted-certs",
  "vm_password_type": "generate"
}

---

• if $bosh[.key] then .value = $bosh[.key] else . end - update model's value only for matched keys
